Ask questions and discuss STM32 wireless solutions and their implementation for running Bluetooth LE, Zigbee, LoRaWAN applications.
Dear all, The X-CUBE-MATTER Expansion Package is now available on our official website following this link MATTER - Matter software expansion for STM32Cube - STMicroelectronics It is a reference implementation for the demonstration of Matter on ST...
Please go and visit our wiki pages where you can find a lot of information on our wireless product families (WB, WBA, WL) and the supported protocols: BLE, Zigbee, Thread, Matter, Lora, ... To begin your technical journey, please start from this top ...
Hi,I have used a custom board with an STM32WB55CG MCU to successfully connect to a Tuya Gateway and also a Homassistent/Zigbee2mqtt setup with the OnOff functionality.As next topic I wanted to add a color control functionility and tried several optin...
Hi, I am currently working with the STM32WB5MMG MCU and looking for some insights regarding its power consumption. Specifically, I would like to know:What is the current consumption when the MCU is in STOP2 mode with the RTC enabled?If anyone has ex...
Hi all,I check with STM32WBA55 datasheet have description can supported external PA. But FW SDK(STM32Cube_FW_WBA_V1.4.0) released notes exist below description. It look Known Limitations is not support EPA, usually need logic control between FEM a...
Hello,First of all, a short text in order to present my problem :After reading all documents about the STM32WL55 and STM32WLE concerning the SubGhz and DMA, I don't find how can I use the DMA and DMAMUX with SUBGHZSPI_TX.Furthermore, I'm working on t...
I check the datasheet and it say that the output impedance os the STM32WB55 is 50 ohms , so i don't must need impedance matching but on the reference design have a pi-match circuit and a RF filter. Really the MCU have a 50 ohms impedance output or th...
Hello,I'm planning to use an STM32WL5X microcontroller in an upcoming project, and I found myself confused on the recommended impedance for external 32MHz oscillators. Please see the attached image for a screenshot from the datasheet.The datasheet sa...
I am refactoring the BLE_OTA sample to work on the WB5M chipset for a custom board. I am moving the call to Delete_Sectors() from boot initialization time to when the OTAS_STM_WIRELESS_FW_UPLOAD characteristic write is performed so that I can erase ...
I have been trying to interface stm32 - nucleo wb55rg development board with mems microphones using SAI interface but I am not even getting the clock on pins specified (PB8) when checked using a DSO, no data on data pin (PC3) either do to this I ha...
I've interfaced my RFM95 LoRa module with the STM32L476RG Nucleo board, using the I-CUBE-LRWAN library to send uplink messages with dummy data and temperature values. However, I can't locate the .ioc file in the library to configure the pinouts for m...
HIWould like to know if advertisement data can be safely changed , while advertising using : ACI_GAP_UPDATE_ADV_DATA Safely meaning , the data is changed as a bulk, and the current advertisement will not show 'half' of the old data and 'half' of the ...
